I go by my nose. When you popped the lid, did it smell sort of like vinegar? If it did, it's probably fine. If it had no smell, I'd be suspect.
The newer stuff in plastic opaque jugs should last indefinitely if kept sealed in a cool dark place.
No propellant issues here...yet. My wife often wondered how come I had all those 8 pound jugs under the bed (now in the closet), Now, she knows why.
I believe, I'd sell the empty can on Flea Bay.
